Word文档字符加密研究及实现

为了增强 Word文档的安全 ,对 Word文档研究了数据级的信息安全问题 ,用面向对象的程序 ,获取Word文档中的字符信息 ,得出其编码 ,按“超长密码钥流”算法进行加密 ,并且在加密解密过程中 ,保持了 Word文档格式信息的无损化 ,也介绍了加密与解密功能的设置。用此方法加密的 Word文档 ,不能被非法破解。该研究使 Word文档的信息安全 ,从底层有了一种更坚固的保障

Encryption Research and Implementation on Word Document Character

The information safety problem of data level of Word document is studied to enhance the safety of Word document.Application of objectoriented program can acquire the character information in Word document and get its encode,and then encrypt it with “over length password key stream”algorithm and keep the form information of Word document not changed,the set up of encryption and decryption function is also introduced,the encrypted Word document by this method can be illegally decrypted.The study can ensure the safety of Word document and it provides a stronger guarantee from the base.
